<P><STRONG>Function</STRONG>
<P>
Sets the offset of a Path Array within the original Field after
partitioning.
<P><STRONG>Syntax</STRONG>
<BR>
<TT><STRONG><BR>
&#35;include &lt;dx/dx.h&gt;<BR>
<P><BR>
PathArray DXSetPathOffset(PathArray a, int offset)<BR>
</STRONG></TT><BR>
<P><STRONG>Functional Details</STRONG>
<P>
Sets the offset value
for a portion of the Path Array
relative to the original grid
to
<TT><STRONG>offset</STRONG></TT>.  In the case where a Path Array
<TT><STRONG>a</STRONG></TT>
is used to define a regular grid of
connections that is a part of a partitioned Field, it is useful to
know the offset of the partition within the original Field.
<P>
Path Arrays are typically used as constituents in Mesh Arrays that
define regular or partially regular connections grids of one or more
dimensions.  In that case, the mesh offsets of the partition within the
original mesh are accessed at the Mesh Array level through calls to
<TT><STRONG>DXSetMeshOffsets</STRONG></TT>
and
<TT><STRONG>DXGetMeshOffsets</STRONG></TT>.
<P><STRONG>Return Value</STRONG>
<P>
Returns <TT><STRONG>a</STRONG></TT> or returns <TT><STRONG>NULL</STRONG></TT>
and
sets an error code.
<P>
Returns <TT><STRONG>o</STRONG></TT> or returns <TT><STRONG>NULL</STRONG></TT>
and
sets an error code.
<P>
Returns <TT><STRONG>OK</STRONG></TT> or returns <TT><STRONG>ERROR</STRONG></TT>
and
sets an error code.
